11. Raw Salmon
Raw food diets are popular right now. Most raw foods are debatable — raw salmon is different. Raw or undercooked salmon (especially from the Pacific Northwest of the United States) can carry a parasite that causes *Salmon Poisoning Disease*.
The name is not exaggerated. Without treatment, this disease can be fatal within two weeks. Symptoms: vomiting, fever, weakness, swollen lymph nodes. The good news? Cooking the salmon kills the parasite — cooked salmon is actually good for dogs in moderation. Same rule for trout from that region. The next one is much milder — time for a small breather.
